It's because your test case calls AC_CONFIG_FILES without arguments.
(M4 will not allow spaces between a macro name and its arguments.) 

I'll commit a patch for this shortly.

 Bonzini> Any clue why the workaround (using nodist) works?

You were right.  That issue was also related to dist_/nodist_.
Conditional definitions led to combinatoric explosion in many places.
Computing *_OBJECTS variables from *_SOURCES was one such place, 
fixed in 1.6.  Computing DIST_SOURCES from *_SOURCES variable
is the one you hit.  But there were other.  1.8 should be clean.
